There's an outfit in Wylie that has an internet offer of "$99 and up" per room for painting, but, that may only be walls, and no moved furniture or the like.
Having been a painting contractor (you need a heart like Job to be good at it), you spend (if professionalism & quality is intended) as much time in the prep as in the actual painting. If you add in the knock-down afterwards, the actual painting time is the least number of manhours.
All back to the old construction adage about of, speed, quality, and cheap you can pick any two of those three, but not all three. Even if you hold your breath and stamp your feet, you can't. Sigh.
